{"id":"CVE-2026-28461","details":"OpenClaw versions prior to 2026.3.1 contain an unbounded memory growth vulnerability in the Zalo webhook endpoint that allows unauthenticated attackers to trigger in-memory key accumulation by varying query strings. Remote attackers can exploit this by sending repeated requests with different query parameters to cause memory pressure, process instability, or out-of-memory conditions that degrade service availability.","aliases":["CVE-2026-32066","GHSA-wr6m-jg37-68xh"],"modified":"2026-04-02T13:26:22.497827Z","published":"2026-03-19T02:16:02.810Z","references":[{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-wr6m-jg37-68xh"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-unbounded-memory-growth-in-zalo-webhook-via-query-string-key-churn"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/openclaw","events":[{"introduced":"0"},{"fixed":"d76b224e20c790b7223d4075abd087c9576a4661"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"2026.3.1"}]}}],"versions":["v0.1.0","v0.1.1","v0.1.2","v0.1.3","v1.0.4","v1.1.0","v1.2.0","v1.2.1","v1.2.2","v1.3.0","v2.0.0-beta1","v2.0.0-beta2","v2.0.0-beta3","v2.0.0-beta4","v2.0.0-beta5","v2026.1.10","v2026.1.11","v2026.1.11-1","v2026.1.11-2","v2026.1.11-3","v2026.1.12","v2026.1.12-2","v2026.1.13","v2026.1.14-1","v2026.1.15","v2026.1.16-2","v2026.1.20","v2026.1.21","v2026.1.22","v2026.1.23","v2026.1.24","v2026.1.24-1","v2026.1.29","v2026.1.30","v2026.1.5","v2026.1.5-1","v2026.1.5-2","v2026.1.5-3","v2026.1.8","v2026.1.9","v2026.2.1","v2026.2.12","v2026.2.13","v2026.2.14","v2026.2.15-beta.1","v2026.2.17","v2026.2.19","v2026.2.19-beta.1","v2026.2.2","v2026.2.21","v2026.2.21-beta.1","v2026.2.22","v2026.2.22-beta.1","v2026.2.23","v2026.2.23-beta.1","v2026.2.24","v2026.2.24-beta.1","v2026.2.25","v2026.2.25-beta.1","v2026.2.26","v2026.2.26-beta.1","v2026.2.3","v2026.2.6","v2026.2.6-1","v2026.2.6-2","v2026.2.6-3","v2026.2.9"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-28461.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
